Buttermilk Loney was the popular name of a long lane stretching for several miles from Shore Road to Ligoniel. The lower end of it corresponds to Skegoneill Avenue today. The name has been revived recently for a short new road in Ballysillan corresponding to an upper section of the old lane.
Buttermilk Loney off Ballysillan Park, BT14 was proposed by Brian Downey, Willowgrove Centre and accepted at the Health and Environmental Services Committee on Monday, 13th August, 2001.
